I'm having a hard time understanding why some of you think the product would not help a fighter???? The exercise strengthens the back of the neck and also the jaw muscle.Victor Ortiz just lost a bout from a broken jaw. Many fighters get their jaw broken in sparring sessions and in bouts. I can't believe the hatefull comments I have read in this forum. I think the hateful comments are made because misery loves company. Not because of the product. If i were to come on the forum and show a bag of rocks with a rope ,artwork and a mouthguard and ask $60 bucks for it..I could understand...but $5 dollars??
Most of the sales I get are from EBAY and i have had many people write to me and comment how great it works.
Why is your jaw and neck any different from theirs?
I bet if Manny Pacquiao invented Rock Jaw ...none of you would hate on it.
